WARNING Cleaning of the air filter and other parts of the air filter involves dangerous work in high places, so be sure to have a service person do it. The cleaning diagram for the air filter is there for the service person, and not for the customer. NOTE A direct current motor is adopted for indoor fan motor in the Concealed Duct Standard Type air conditioner. Caused from its characteristics, a current limit works on the direct current motor. When replacing the highperformance filter or when opening the service board, be sure to stop the fan.
